SHEET-METAL Box.

SPECIFICATION forming part of Letters Patent No. 426,378, dated April22, 1890.

Application filed January 30,1890. Serial No. 888,557. (No model.)

T0 on whom it may concern.-

Be it known that 1, CHARLES J. HAUOK, J12, a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented new and useful Improvements in Sheet-Metal Boxes, ofwhich the following is a specification.

This invention relates to a box the body of which is made of a singlepiece of sheet metal and provided with double sides and with flangesformed on its front and made to overlap its back. lVith the rectangularbody of the box is combined a hinged cover provided with elastic earswhich are constructed to hug the sides of the box, so as to retain thecover in its closed position.

In the accompanyin g drawings, Figure 1 represents a face view of theblank from which the body of my box is formed. Figs. 2, 3, 4, and 5illustrate the different stages through which the blank passes in orderto complete the body of the box. Fig. 6 is a face view of the box whenthe cover is partly raised. Fig. 7 is a horizontal section in the planean m, Fig. 6. Fig. 8 is a transverse vertical section in the plane y 3Fig. 7. Fig. 9 is a vertical section in the plane 2' .2, Fig. 8. Fig. 10is a face View of the blank from which the cover is formed.

' In the drawings, the letter A designates the blank from which the bodyof my box is made. The section a between the dotted lines 10 and 11forms the bottom of the body. The section 1) between the dotted tlines12 and 13 forms the back. The sections 0 coutside of the dotted lines 12and 13, respectively, form the inner portions of the duplex sides. Thesection (Z between the dotted lines 14. and 15 forms the front. Thesections e a between the dotted lines 14: and 16 and 15 and 17,respectively, form the outer portions of the duplex sides, and thesections ff outside of the lines 16 and 17 form the overlapping flanges.The blank A is then bent successively in the lines 12 la and 13 15 thenin the lines 10 11, and then in the lines 16 17 to the forms shown inFigs. 2 to 5, and those portions of the sides e e which extend slightlybeyond the line 11, Fig. 1, are bent inward toward the bottom, so as torender the box tight. By referring to Fig. 7 it will be seen that eachof the sides of the body is composed of a section 0 and a section e, andin order to render the body strong and durable the sections fare bentover the back of the box. (See Figs. 5 and "7.)

After the body of the box has been completed the tongueextension g 011the top edge of the back i) is convoluted or rolled to form an eyecorresponding to the eyes of the cover B, so that by passing a wirethrough said eyes a hinge-joint is formed between the cover and thebody. In the top edge of the front (I of the body is formed afinger-opening h.

The cover B is formed of a blank such as shown in Fig. 10. The section iof this blank forms the top of the cover, and it is provided withextensions t" i to form the eyes for the hinge-joint. The section jforms the front and the sections 7c 7:; form elastic ears which hug thebody of the box when the cover is closed, and which serve to retain saidcover in its closed position. The top edges of the outer side sections 6e are rounded or beveled off (see Fig. 9) to enable the cars 7a to snapover the sides of the body.

lVhatI claim as new, and desire to secure by Letters Patent, is-

1. A box consisting of a rectangular body having the front provided witha finger-opening in its top edge and the back formed with a convolutedtongue-extension, and the lid or cover hinged to said. extension andcomprising the section 1', to form the box-top, the section 3' at anangle thereto to overlie the front finger-opening, and the elastic sideears k, to clasp the upper ends of the box-sides, substantially asdescribed.

2. A sheet-metal box consisting of a body comprising duplex sides,flanges f, formed on the front cl and overlying the back I), aconvoluted tongue-extension g on the top edge of the said back, and afinger-opening h in the top edge of the said front, and the lid or coverB, hinged to the tongue-extension and comprising the section 2', to formthe box-top, the section j at an angle thereto to overlie thefinger-opening, and the elastic ears on the latter section to clasp theupper ends of the duplex sides, substantially as described.

In testimony whereof I haveherennto set my hand in the presence of twosubscribing witnesses.
